Patent number: 11424655Abstract: A drive device includes an annular cover having an inner peripheral opening, and a drive unit to which the annular cover is attached. The drive device includes an inner peripheral adhesive that bonds the inner peripheral end of the annular cover to the drive unit, and includes an outer peripheral adhesive that bonds the outer peripheral end of the annular cover to the drive unit. Therefore, the drive unit and the annular cover can be bonded to each other at a plurality of locations. Therefore, it is easier to firmly fix and fix the components to each other as compared with a configuration in which the only one bonding location is provided. Therefore, it is possible to provide the drive device in which components are properly adhered and fixed to each other.Type: GrantFiled: May 14, 2020Date of Patent: August 23, 2022Assignee: DENSO CORPORATIONInventors: Gou Kawaguchi, Naohiro Yamamato
